REINFORCED 9” FORD AXLE HOUSING
Summers Brothers takes select 9” Ford axle housings, removes the tubes, fish mouths the banjo ends and installs heat treated molybdenum tubes, then directly gussets the inside ends of the tube to the inside of the banjo, forming a very strong and stiff structure. These housings are custom made to your specs, and are sold outright. Call for ordering information.

SPOOLS BY SUMMERS BROS.
Summers Brothers spools are available in most standard spline sizes as well as oversize spline sizes. They are usually 2/3 the weight of a standard differential and are maintenance free. Manufactured from chrome molybdenum steel and
hardened for strength and wear resistance, they are carefully designed for minimum weight and maximum stiffness. Ring and pinion gear life is enhanced with the spool’s use due to the spool’s great stiffness.

HIGH STRENGTH FORGED ONE-PIECE JEEP AXLE KIT
1976 and later Jeep CJ-7 and CJ-5 rear axles are two-piece axles with the flange keyed to the shaft. These axles are very prone to axle key shearing. When this happens, the jeep is immobilized and the whole axle shaft assembly must be replaced.

Summers Brothers offers a solution: a one-piece forged nickel steel axle that
has no joint. This axle not only eliminates the joint problem, but it is also of
superior strength due to its chrome nickel alloy composition.

Axle kit includes: two forged axles, two bearing abutment rings, two bearing retainer flanges (seals installed),
two Timken tapered roller bearings, two bearing collars, two oversize housing seals and instruction sheet.
